Drug Interaction Report

Using filgrastim during or too soon after completion of a course of ixazomib may alter the effects of either medication. Filgrastim should generally not be given within 24 hours before or 24 hours after cancer chemotherapy. Talk to your doctor if you have any questions or concerns. It is important to tell your doctor about all other medications you use, including vitamins and herbs. Do not stop using any medications without first talking to your doctor.

Food may interfere with the absorption of ixazomib, which may lead to lower blood levels of the medication and possibly reduced effectiveness. You should take ixazomib at least 1 hour before or 2 hours after eating. On days when you take both ixazomib and dexamethasone, make sure you do not take them at the same time, since ixazomib should be taken on an empty stomach while dexamethasone should be taken with food to prevent irritation and injury to the stomach.
